Make the peek method behaviour in the path selector deterministic #598

[CaelmBleidd]

Description

Make a behaviour of the peek method of the path selector determenistic. To do it we fix taken random value between poll calls, so any sequence of the peek methods (and one following poll call) will take the same element of the queue.

Fixes #598

Type of Change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Automated Testing

Any test for collections that try to find NoSuchElementException.

Manual Scenario

You can set a debug point at any place where there are several elements in the path selector's queue, and call peek method multiple times. Check that it doesn't calculate a random value every time and returns the same value all the time.
